Where to get lots of cheap 3-4 y.o. PJs (not necessarily new)?

[AngelDog]

I want a whole load, as we use PJ trousers as indoor trousers which DS wears instead of nappies. I don't want character ones eg Thomas the Tank Engine etc.

I can't see any bundles on Ebay - individual PJ sets are about £6.

Local charity shops / Freecycle haven't been any good.

Our NCT sale isn't for another month or two and we need them now as DS is 2.8 and his existing ones are really, really small.

Any ideas?

Primark are usually pretty cheap.

i second primark. or asda.

I am a real bargain hunter and buy most of my daughters clothes "pre-loved" I have found some great bargains on the selling pages of Facebook. One in particular;

They sell 100's of childrens clothes from newborn up to 13years, their prices are great and they are really helpful ladies.

Other than that I'd say Ebay, the only trouble with that is you never know if you're going to get outbid at the last minute which is really annoying!!
